Clinical Utilities

Diagnose early H pylori infection in patients with gastric and duodenal disease. Circulating antibodies to H pylori are predominantly of the IgG class. A systemic response of the IgA type is usually less pronounced but, if significant, may indicate a more severe inflammation. A few patients develop only antibodies to IgA. Antibodies to IgM, although rare, may indicate an early infection.
